Model MICS-EK1 -Metal Oxide Semiconductor Gas Sensor Evaluation Kit
Simply attach the universal power supply, connect to a PC USB port and plug in one or two gas sensors. The SGX data logging and control software allows the performance of different sensors to be assessed and makes it easy to capture performance data.
The SGX MICS-EK1 Gas Sensor Evaluation Kit will drive the SGX range of Metal Oxide Semiconductor gas sensors and automatically measure the sensor resistance as it changes with applied gas.
Sensors can be driven manually or automatically by sending simple commands through the USB interface to an on-board microcontroller. A comprehensive set of commands is provided for use with a terminal program such as HyperTerminal. Alternatively an easy-to-use control and data logging PC application is provided on CD which gives full functionality in a few mouse-clicks.
Surface mount adapter boards are also available with the kit and can be ordered separately. One adapter PCB will plug in to both sockets and can be fitted with either a single or dual surface mount gas sensor.
The heaters can be set to two levels. These are nominally preset to 43 mW and 76 mW by plug-in resistors but may be changed by the user to other values. The microprocessor monitors the sensor output resistance with automatic resistance range switching.
An expansion connector provides access to four configurable alarms (open collector), two analog outputs and four digital inputs. LEDs on the board mimic the status of each alarm. A JTAG header allows advanced users to upload their own software to the microcontroller (MSP430F2616) and make full use of the available interfaces.
A universal mains adapter is also supplied or the user may connect a 9 V power supply to the terminal block connector.
